Expert Review: S17 High-Power 20Ah Fat Tire E-Bike

S17 is best understood as the big-battery high-output model.

The strongest reasons to consider it are strong acceleration, large battery capacity, and rough-route traction.

The tradeoffs are high weight and route-limit complexity, so choose it for the right route and storage situation.

StreetRides Expert Video Takeaway

AOSTIRMOTOR S17 1500W Review Canada | Suspension, Settings & Speed Test

We Try Motorsports reviews the AOSTIRMOTOR S17 1500W in a hands-on video covering the display, advanced settings, riding impressions, braking, rear-shock behaviour, riding-mode changes, top-speed testing, average speed, and the final verdict. This makes the review useful for buyers who want to understand setup and control, not only the headline motor number.

The S17 is an interesting choice for rough Canadian access roads, gravel, potholes, and outdoor routes because the current Street Rides page describes front and rear suspension. Compared with a simpler hardtail, extra suspension can improve comfort and control over uneven ground, but it also adds weight, moving parts, and maintenance considerations. The video’s rear-shock discussion helps shoppers decide whether that trade-off suits their riding.

The current Street Rides page lists a 1500W motor, 48V 20Ah battery, 26 x 4.0 inch tires, and up to 50 km/h. The video confirms the S17 and 1500W model name, but does not independently verify every current battery, tire, range, or speed specification. Treat the page range figures as estimates, since hills, temperature, rider weight, tire pressure, terrain, assist level, and throttle use all affect distance.

The video is from 2022, so component revisions may exist. Confirm the supplied configuration before ordering. The listed power and advertised speed may exceed common Canadian public-road e-bike limits; check provincial and municipal rules before using the bike on public roads, bike lanes, or shared trails.
